This sounds gross. To duplicate; u8500_clk_init(), u8540_clk_init() and u9540_clk_init() just for the sake of loading a few pointers into an array for a small part of the development cycle sounds obscene. I genuinely think keeping the current patch in this series and then removing the clk_register_clkdev() in the remove ATAG support series is the best way to go. If you think I'm wrong then I'll so as you ask however.
